Conceptual metaphor

Conceptual metaphor is the claim, developed by George Lakoff and Mark Johnson in Metaphors We Live By (1980), that abstract thought is structured by systematic mappings from concrete, embodied experience onto abstract domains. The canonical example: ARGUMENT IS WAR — English speakers say arguments are attacked, defended, won, and lost; positions are indefensible; claims can destroy or demolish an opponent's view. This is not merely stylistic ornamentation. On Lakoff and Johnson's account, the metaphor structures the conceptual domain itself: speakers who use war language for argument are not describing a pre-existing concept of argument, they are thinking in terms of warfare.

The framework is a descendant of linguistic relativity and a challenge to formal semantics: it proposes that meaning is not computed from abstract logical representations but grounded in bodily and cultural experience. Conceptual structure is not arbitrary but motivated by the structure of human bodies and their typical environments — hence the cross-linguistic prevalence of metaphors mapping UP to more, good, and conscious, and DOWN to less, bad, and unconscious, which plausibly reflects the spatial structure of embodied experience.

The framework's empirical vulnerability: it is often unclear whether conceptual metaphor theory is a claim about thought or about language. Evidence that speakers use war language for argument does not establish that they think about argument in war terms rather than merely expressing it that way. Psycholinguistic experiments have attempted to probe this distinction, with mixed results. The theory's ambition — to ground all of abstract cognition in embodied metaphor — has outrun the evidence, though the core observation that abstract vocabulary is historically derived from concrete vocabulary is well-established and genuinely illuminating.
